ics/scada perl tool for ModBus and DNP3 devicesScadaScan finds SCADA slaves in the network. The tool works on the IP range that is provided on command line and currently supports enumeration of DNP 3 and Modbus slaves. In the Modbus mode the tool bruteforces the first unit ID (or slave ID) by sending ‘Modbus Read Register’ message. In the DNP mode the tool sends a DNP ‘Request Link Status’ message to DNP slaves. The tool can be used to map Modbus and DNP 3 slaves in scada network. The next release of ScadaScan will support scanning of SCADA Master and will have vulnerability detection capabilities for multiple SCADA Master Systems.
